In the past few years, service providers have observed a pronounced increase in traffic associated with gaming downloads. Newer consoles such as the Xbox One and PlayStation 4 have sufficient onboard storage to enable gamers to download new games rather than buy them on disc. These graphically intense games are large files, and gaming traffic will reach 4 percent of all IP traffic by 2022. Furthermore, these downloads tend to occur during peak usage periods, with gaming downloads reaching up to 8 percent of busy hour traffic. We expect the growth of gaming traffic to continue, and gaming is one of the forms of traffic that will limit the likelihood that video traffic will exceed the projected 82 percent by 2022.
While these models have diminished in mature e-commerce and online advertising markets they are still prevalent in some more nascent industries. China is one example where Affiliate Marketing does not overtly resemble the same model in the West. With many affiliates being paid a flat "Cost Per Day" with some networks offering Cost Per Click or CPM.
Although the number of connections is growing 2.4-fold, global M2M IP traffic will grow more than sevenfold over this same period, from 3.7 EB per month in 2017 (3 percent of global IP traffic) to more than 25 EB by 2022 (6 percent of global IP traffic; refer to Figure 12). The amount of traffic is growing faster than the number of connections because of the increase of deployment of video applications on M2M connections and the increased use of applications, such as telemedicine and smart car navigation systems, which require greater bandwidth and lower latency.
Hotels, cafes, and restaurants will have the highest number of hotspots by 2022 globally, and the fastest growth is in healthcare facilities (hospitals), where hotspots will triple over the forecast period. The primary objective of Wi-Fi in hospitals is to improve the delivery of healthcare services and staff productivity, with a secondary benefit being Internet access for patients, their families, and their guests.
Internet of Things (IoT) is no longer a phenomenon, but it has become a prevalent system in which people, processes, data, and things connect to the Internet and each other. Globally, M2M connections will grow 2.4-fold, from 6.1 billion in 2017 to 14.6 billion by 2022 (Figure 10). There will be 1.8 M2M connections for each member of the global population by 2022.
